CBN grinding wheel for HSS broaching tool

Broaching is a machining process that removes material from a workpiece using a toothed cutting tool called a broach. Broaching is used to machine round and non-round holes, as well as the outer contours of various workpieces.

Broaching can be classified into internal surface type and internal surface type, depending on whether the broaching removes material from the inside or outside of the workpiece. Moresuperhard  produce all standard types of CBN grinding wheels for production or re-sharpening of broaching tools.

Material of broaching tools:

-HSS (High Speed Steel)

-PM HSS (Powder Metallurgy High Speed Steel

PM HSS is more suitable for machining very hard and more diffultly machineable materials like e.g. titanium); tungsten carbide (for rare purposes of machining cast iron).

Type of broach:Round broaches, Helical broaches,Spline broaches,Keyway broaches,Internal hole,Flat broaches
